Not freshly built, is about 3 years old. It was working fine yesterday. I believe it is not posting, as i get no signal from other monitors, and i know for a fact these monitors are working (tried them with a different pc) i have cleared the bios many times, reseated everything, tried entering safe mode, (power on/off 3 times), tried a different monitor from the 3 i knew were working (tried a 4th). I am lost. I get no motherboard splash screen, i can't enter bios. No signal to monitors whatsoever. No online troubleshooting, including the one pinned in this section, worked.
